Circuit/System Description

For an overview of the component/system, refer to:

The solenoid valve directs fluid pressure to the 1-2-3-4 regulator valve that controls the fluid pressure to the 1-2-3-4 clutch.

DTC P2723, P2724 will set with a hydraulic/mechanical condition.

Circuit/System Verification

Danger: If DTC P2724 is present, the vehicle could have forward propulsion while in neutral. Failure to keep the brake pedal depressed while starting or shifting through the gear ranges may cause the vehicle to move forward resulting in potential vehicle damage and possibly injury or death.

  1. Verify the condition does not exist:Incorrect fluid level or condition»Refer to:Transmission Fluid Level and Condition Check
    • If a condition exists

      Repair or replace as necessary

    • If no condition exists
  2. Ignition » On / Vehicle » In Service Mode
  3. Clear the DTCs.
  4. Road test the vehicle.»Refer to:Road Test

    Verify DTC P0716, P0717, P0722, P0723 is not set

    • If none of the DTCs are set
  5. Verify DTC P2723, P2724 is not set
    • If DTC P2723 or P2724 is set

      Refer to:Circuit/System Testing

    • If none of the DTCs are set
  6. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

    Verify the DTC does not set.

    • If the DTC sets

      Refer to:Circuit/System Testing

    • If the DTC is not set
  7. All OK.
Circuit/System Testing
  1. Verify the condition does not exist:Incorrect pressure»Refer to:Line Pressure Check&Solenoid Valve Pressure
    • If no condition exists
  2. Ignition/Vehicle » Off
  3. Remove the component:Q8 Control Solenoid Valve Assembly
  4. Verify the procedure/test passes.»Refer to:Control Solenoid Valve and Transmission Control Module Assembly Solenoid Performance Test
    • If the procedure/test does not pass

      Replace the component:Q8 Control Solenoid Valve Assembly

    • If the procedure/test passes
  5. Refer to:Diagnostic Fault Information
